PerkinElmer Capillary Column Graphite Ferrules, 1/8in Nut Size, 0.32mm column i.d., 0.5mm (2-hole) Ferrule i.d., Pkg 10 - 09903395

Capillary Column Graphite Ferrules, 1/8in Nut Size, 0.32mm column i.d., 0.5mm (2-hole) Ferrule i.d., Pkg 10. This is the ferrule of choice for high-temperature applications. Of the three ferrule types available graphite is the softest, making it less damaging to capillary columns when over tightened. Graphite seals easily and does not stick to glass columns. Recommended for use with capillary columns. Temperature limit is 450°C. Note: 0.25-0.32mm inner diameter. Columns require 0.5mm inner diameter ferrules. 0.53mm inner diameter columns require 0.8mm inner diameter ferrules.
